A Collaborative
Study
The project is a collaborative study involving
three PIs (Principal Investigators): Tobias
Fischer (University of New Mexico), Jim
Walker (Northern Illinois University) and David
Hilton (Scripps Institution of Oceanography, La Jolla, California).
Fischer is a volcanologist specializing in volcanic gas chemistry.
His role is to characterize the constituents of the volcanic output
and derive fluxes of individual chemical species (nitrogen, sulfur,
etc) along the length of the subduction zone. Walker is a petrologist
with wide experience of working in central America. He will focus
on the chemistry of the lavas: in particular, characterizing their
fluid contents thereby providing complementary information to that
gained from the volcanic gases. Hilton is a geochemist with expertise
in isotopic studies. Working on both volcanic gases and lavas, he
will provide information on the sources of the volatiles (subducted
slab sediment, underlying mantle or arc-crust). Together, the scientific
team (and their students) will built a detailed picture of the volatile
systematics — sources and sinks — of this fascinating subduction
zone.
